I don't actually know what the standard would mandate in this case
(conversion from 'const int &' to 'int *'), but this is clearly at least
confusing (stripped down and condensed testcase from this report):
-----------------------------------
void f(int* pn);
struct Foo {
static void f(int* pn);
};
int main() {
const int null = 0;
f(0); // ok
f(null); // ok
Foo::f(0); // ok
Foo::f(null); // compile error
}
----------------------------------
The compiler only gives an error on the call to Foo::f(), not on ::f(),
although they have the same signature. For present CVS and 3.2, the error
message is
x.cc: In function `int main()':
x.cc:14: error: invalid conversion from `int' to `int*'
x.cc:14: error: initializing argument 1 of `static void Foo::f(int*)'
Regards
Wolfgang
